. WEATHER-STRIP.

Specification 01' Letters Patent.

Patented Dec. 30, 1913.

I application filed December 11, 1911. Serial No. 665,015.

To all whom it may concern Be it known that LFR'AN S. BLooM, a citizen of the United States, residing at Burlington, in the county of Des Moines and State of Iowa, have invented certain new and useful Improvements in WeatherTStrips, of which the following is a specification;

This invention relates to Weather strips and has for its object to provide a device of this character of simple construction especially adapted to be applied to the doors of refrigerator cars.

In the accompanying drawings, Figure 1 is a perspective view ofthe doors of a refrigerator car" illustrating a manner in which the strip may be applied. Fig. 2 is a longitudinal sectional view of part of the strip. Fig. 3 is a' transverse sectional view of the same cut on the line'4=-4 on Fig. 2.

Referring more particularly to the draw-' ings in which like numerals designate like parts throughout, my invention is described as follows: The device consists of an outer board 1 and an inner board 2, said inner board being of a greater widththan said outer board. Said outer board is covered with a suitable form of packing 3, such as raw cotton or the like. Said packing 3 is in turn covered by duck or canvas 4, which canvas extends slantingly inward from the edges of the outer board 1, to the edges of the inner board 2, contacting the latter, and is turned against the under face of the inner board to which it is secured by any suitable means adapted for the purpose. A recess 5 is cut in the door or door frame as the case ma be, which recess receives the device, one wail 6 of the recess conforming to the adjacent slanting edge of the device while a wedge 7 is inserted between the straight wall 8 of the recess and the oppositely slanting edge of said device or that edge which is most adjacent to the wall 8. Theedge of the wedge 7 which contacts theadjacentedge of the device is so slanted, as it' extends downward, as to conform therewith. Said wedge is held removably in position by means of a. plurality of screws 9 or other suitable means.

Coil or helical springs 10 are interposed between the outer board 1 and the wall .'1 of the recess 5, said springs passing through respective corresponding perforations 12 which are provided in the innerboard 2 'of said device. Said springs have suitable seats in the wall 11 of the recess 5-and in the in-' ner face from its of said board 1, which seats aid in securing them against movement. Said springs are for the purpose of normally securing the device in its extreme outward position and resist the pressure exerted by the frame of said door or the edge of the door whenthe door is in closed position, thereby effectively causing such openings as would occur to be air tight thereby preventing the entrance of warm air or any other kind of air into said refrigerating car or other refrigerating device or plant or at any other place where said device is utilized.

When it is desired to remove the device position in the car door or door frame or other place, for any cause, the

.screws 9 are removed when the wedge 7 may be removed from position,-thereby permitting the device to be easily removed from its place in the recess 5. It will be seen that as long as the wedge '7 is in position it is practically impossible for the device to be removed or to get out of its proper position.

It will be seen that when the device is applied to a refrigerating car door, it is necessary to construct the Walls of the frame of said door in such manner that they converge as they extend inward. The contacting edges of the doors are also slanted in such manner that the door upon whose outer edge the device is applied must be closed first, so that the outer edge of the opposite door will contact such device on bein swung into closed position.

Although I have specifically described the novel features of construction, combination and arrangement of the several parts'of my invention, yet I do not confine myself to such specific construction, combination and arrangement of parts but reserve and may exercise the right to make such changes therein as do not depart from the spirit of the invention or the scope of the appended claim.

Having described my invention what I claim as new and desire to secure by Letters Patent, is:

In combination with a supporting object having a recess one side wall of which is approximately at a right angle to the bottomof the recess and the opposite side wall inclined at an acute angle to the bottom of the recess, a weather strip comprising inner and outer boards, the inner board being belfOlate'd and bein n-F nrnnl nh h-rm cess, said member bearing against one side portion of the flexible material and holding the other side portion thereto against the 15 side wall of the recess which is inclined at an acute angle to the bottom of the recess.

In testimony whereof I afiix my signature in presence of two Witnesses.
